Correct.

The attacker in the 2015 OPM hack acquired biometric data on every federal government employee. Cross referencing against biometrics collected at ports-of-entry unmasked covert US operations, undermined US interested and put the lives of Americans abroad at risk. This information is valuable to every adversary equipped to use it.

The scandal of Tiktok is that rather than breaching OPM, a foreign entity has simply requested this information directly from future federal employees. Beyond mere facial biometrics, tiktok knows the childhood street address of ~every future spy -- and everyone near and dear to them. Tiktok can generate a psychological profile on ~every future diplomat and international businessman. And the biometrics they can access includes things like sleeping habits, gait, vocal chord structure, vocabulary, and accent -- much more than the OPM hackers got.
